# Bounds::GetVolume ```cpp float GetVolume() const ``` 计算包围盒的体积。返回 `extents.x * 2.0f * extents.y * 2.0f * extents.z * 2.0f`。 **返回:** `float` - 包围盒体积 **线程安全:** ✅ **复杂度:** O(1) **示例:** ```cpp #include #include using namespace XCEngine::Math; Bounds bounds(Vector3(0.0f, 0.0f, 0.0f), Vector3(1.0f, 2.0f, 3.0f)); float vol = bounds.GetVolume(); // vol = 2 * 4 * 6 = 48 ``` ## 相关文档 - [Bounds](bounds.md) - 返回类总览
